Cursed Talon

You may sacrifice a creature you control with
flying rather than pay Cursed Talon's casting
cost.
At the beginning of your upkeep, if you have
more creatures with flying in play than your
opponent, Summon a 1/1 Crow creature token
with flying. If you have no creatures with flying
in play, Sacrifice Cursed Talon and it deals 3
damage to you.
